Addition and Place Value Concepts

Mrs. Walker teaches students how to add numbers vertically using place value disks. The lesson includes solving three problems: 303 + 37, 211 + 95, and 324 + 156. Students learn to use mental math and manipulatives to simplify addition. The video concludes with instructions for independent practice.
